Practical Notes

When selecting or designing office furniture, maintain a vertical clearance of approximately 280 mm to 300 mm between the chair seat height and the table top.

BIM modelers should utilize these dimensions as baseline constraints when creating standard parametric furniture families for commercial projects.

Always account for castor wheels or floor glides if added post-manufacture, as they can alter the functional ergonomic height of the chair or table.
